osgGLUTGetVersion() returns the library version number.
Numbering convention : osg_src-0.8.31 will return 0.8.31.

<P>This C function can be also used to check for the existence of the OpenSceneGraph
library using autoconf and its m4 macro AC_CHECK_LIB.

<P>Here is the code to add to your configure.in:
\verbatim
#
# Check for the OpenSceneGraph (OSG) GLUT library
#
AC_CHECK_LIB(osg, osgGLUTGetVersion, ,
[AC_MSG_ERROR(OpenSceneGraph GLUT library not found. See http://www.openscenegraph.org)],)
\endverbatim</BLOCKQUOTE>
